Application July 5, 1955, Serial No. 519,896

1 Claim. (Cl. 248-129) This invention relates to a novel mobilereceptacle support and more particularly to a support for cans, largebuckets, barrels and other receptacles having a recessed bottomsurrounded by a depending flange.

A primary object of the present invention is to provide a support whichmay be readily secured to receptacles of difierent cross sectional sizesbeneath the bottom thereof for supporting the receptacle in a slightlyelevated position and with the center of gravity thereof as low aspossible to thus provide an extremely stable mobile support.

A further object of the invention is to provide a support of theaforedescribed character which will be substantially concealed when inan applied position, yet which will enable a receptacle supportedthereby to be readily moved on the surface engaging wheels of thesupport.

A further object of the invention is to provide a receptacle supportwherein the weight of the receptacle and its contents will be supportedprimarily adjacent portions of the periphery of the receptacle directlyover the support wheels, so that the support can be made extremely lightin weight yet capable of sustaining a substantial weight.

A further object of the invention is to provide a mobile support whichmay be very economically manufactured and sold yet which will beextremely efficient and durable in use.

Other objects and advantages of the invention will hereinafter becomemore fully apparent from the following description of the drawing,illustrating a presently preferred embodiment thereof, and wherein:

Figure 1 is a fragmentary side elevational View partly in verticalsection of the lower portion of a cam or receptacle shown mounted on andsecured to the mobile support;

Figure 2 is an enlarged top plan view of the support,

and

Figure 3 is a fragmentary sectional view of the support applied to thebottom portion of a receptacle and taken substantially along a plane asindicated by the line 3-3 of Figure 2.

Referring more specifically to the drawing, the mobile support in itsentirety and comprising the invention is designated generally 5 andincludes a substantially flat plate 6 which is preferably of triangularshape, as illustrated in Figure 2. The plate 6 is provided withelongated slots 7 which align with the three corners thereof and theouter ends of which are spaced inwardly from said corners. The plate 6is provided with an opening 8 between each of its corners and theadjacent slots 7, as seen in Figure 3.

The support 5 also includes three corresponding elongated arms 9 each ofwhich is provided intermediate of the ends thereof with an elongatedslot 10. The arms 9 are provided adjacent inner ends thereof withopenings 11. The arms 9 are disposed in alignment with the three cornersof the plate 6 and have their inner ends overlying said plate. Bolts 12extend downwardly through 2,808,220 Patented Oct. 1, 1957 the openings11 and loosely through the slots 7 disposed therebeneath and have theirheads countersunk in the upper ends of the openingsll, as seen in Figure3. A nut 13 threadedly engages the lower end of each bolt 12 andsupports a washer 14 which is disposed on the bolt between the nut andthe underside of the plate 6 and which is of a diameter substantiallygreater than the width of the slot 7.

Similarbolts 15 extend downwardly through the slots 10 and the openings8 and have nuts 16 threaded on their lower ends and support washers 17which are disposed between said nuts and the underside of the plate 6.The upper edges of the side walls of the slots 10 are beveled as seen at18 for countersinking therein the heads of the bolts 15; so that theheads of the bolts 12 and 15 will be disposed substantially flush withthe upper surfaces of the arms 9, as seen in Figure 3.

The other outer end portions of the arms 9 extend outwardly from thecorners of the plate 6. A caster, designated generally 19, is swivellymounted beneath and supports the outer end of each arm 9. Each caster 19includes a frame or fork 20 which is swivelly disposed beneath an arm 9and swivelly connected thereto by a headed kingbolt 21 which is swivellymounted and countersunk in said arm. A caster wheel 22 is journalled ineach frame or fork 20. At least the peripheral or tread portion of eachwheel 22 is formed of rubber.

A portion of the lower part of a receptacle 23, such as a can, isillustrated in the drawing and includes a substantially flat bottom 24.The can or receptacle 23 has a bottom flange 25 to which the bottom 24is secured and which extends downwardly from the plane of said bottomand is disposed completely around the receptacle, as is conventional.

The bottom portion of the receptacle 23 is applied over the mobilesupport 5 so that portions of the bottom 24 thereof rest on the arms 9.With the nuts 13 and 16 loosened, the arms 9 can be extended outwardlyrelative to one another, by the bolts 12 sliding in the slots 7 and bythe slots 10 of the arms 9 sliding relative to the bolts 15 until theouter end surfaces 26 of the arms 9 abut against the inner side of theflange 25. With the arm ends 26 abutting tightly against the inner sideof the flange 25, the nuts 13 and 16 are tightened for securing thesupport 5 to the flange 25 so that the arms 9 thereof will abut againstthe underside of the bottom 24. With the receptacle 23 thus applied tothe support 5, bottom portions of the caster wheels 22 will dependsufiiciently below the bottom edge of the flange 25 for supporting thereceptacle in a slightly elevated position so that when w the receptacleis pushed it will roll with the support 5 on the wheels 22 to facilitatemovement of the receptacle. The casters 19 are spaced sufliciently fromthe outer arm ends 26 to allow said castors to swivel through a completecircle without contacting the flange 25.

While the support 5 is adjustable for fitting cans or receptacles ofdifferent cross sectional sizes, said support may also be made indifferent sizes, each of which is capable of fitting receptacles of arange of sizes. It will also be apparent that the plate 6 may be of anydesired shape.

Various other modifications and changes are likewise contemplated andmay obviously be resorted to, without departing from the function orscope of the invention as hereinafter defined by the appended claim.
